• EMC Radiation/Noise Resistance: EN61326-1:2006, EN61326-2-3:2006 • LKM 261 Digital Programmable Measurement Transducer • The LKM 261 is a digital programmable measurement transducer for standard rail mounting applications.　This transducer can be programmed for various thermocouples conforming to DIN EN60584-3 The LKM 261 converts the temperature-dependent thermal voltage of the sensor into a standard signal in the range 4 → 20 mA.　Temperature compensation is applied to the measurement transducer.　This transducer can be programmed using the generic interface type LKM S1 available from RS.　You can make some visual corrections directly using the adjustment controller.
